Extract Vanadium and Molybdenum from Spent Catalyst

Abstract: Based on the analysis of the properties of spent catalyst, extract vanadium and molybdenum from spent catalyst by roasting alkaline leaching. Sodium carbonate was leaching agent. The effects of roasting temperature, roasting time, the concentration of sodium carbonate and the number of leaching times on the leaching rate of vanadium and molybdenum were studied. Roasting temperature of 650°C, roasting time of 3h, the concentration of sodium carbonate of 50g/L and once counter-current leaching, under this condit… Show more

“…The source rocks in East Sag are favorable for the hydrocarbon generation. The high maturity gas is also detected in the coal measure strata [15]. The isothermal adsorption experiment of the shale of 3rd member of the Shahejie Formation in East Sag shows that the average gas adsorption quantity is 1.…”
